MFC r309412,r316109,r316132:
r309412 (by imp):
dd is currently a bootstrap tool. It really doesn't have any business being a bootstrap tool. However, for reproducible build output, FreeBSD added dd status=none because it was otherwise difficult to suppress the status information, but retain any errors that might happen. There's no real reason that dd has to be a build tool, other than we use status=none unconditional. Remove dd from a bootstrap tool entirely by only using status=none when available. This may also help efforts to build the system on non-FreeBSD hosts as well.
r316109:
Don't hardcode input files for stage 1/2 bootloaders; use .ALLSRC instead
This is a better pattern to follow when creating the bootloaders and doing the relevant space checks to make sure that the sizes aren't exceeded (and thus, copy-pasting is a bit less error prone).
r316132:
Parameterize out 7680 (15 * 512) as BOOT2SIZE, similar to sys/boot/i386/zfsboot/...
This is being done to make it easier to change in the future--this action might be needed sooner rather than later because of gcc 6.3.0 bailing, stating that there is negative free space left (deficit) in the boot2 bootloader. |

Merge multi-FIB IPv6 support from projects/multi-fibv6/head/:
Extend the so far IPv4-only support for multiple routing tables (FIBs) introduced in r178888 to IPv6 providing feature parity.
This includes an extended rtalloc(9) KPI for IPv6, the necessary adjustments to the network stack, and user land support as in netstat.

With retirement of cpumask_t and usage of cpuset_t for representing a mask of CPUs, pc_other_cpus and pc_cpumask become highly inefficient.
Remove them and replace their usage with custom pc_cpuid magic (as, atm, pc_cpumask can be easilly represented by (1 << pc_cpuid) and pc_other_cpus by (all_cpus & ~(1 << pc_cpuid))).
This change is not targeted for MFC because of struct pcpu members removal and dependency by cpumask_t retirement.

etire the cpumask_t type and replace it with cpuset_t usage.
This is intended to fix the bug where cpu mask objects are capped to 32. MAXCPU, then, can now arbitrarely bumped to whatever value. Anyway, as long as several structures in the kernel are statically allocated and sized as MAXCPU, it is suggested to keep it as low as possible for the time being.
Technical notes on this commit itself: - More functions to handle with cpuset_t objects are introduced. The most notable are cpusetobj_ffs() (which calculates a ffs(3) for a cpuset_t object), cpusetobj_strprint() (which prepares a string representing a cpuset_t object) and cpusetobj_strscan() (which creates a valid cpuset_t starting from a string representation). - pc_cpumask and pc_other_cpus are target to be removed soon. With the moving from cpumask_t to cpuset_t they are now inefficient and not really useful. Anyway, for the time being, please note that access to pcpu datas is protected by sched_pin() in order to avoid migrating the CPU while reading more than one (possible) word - Please note that size of cpuset_t objects may differ between kernel and userland. While this is not directly related to the patch itself, it is good to understand that concept and possibly use the patch as a reference on how to deal with cpuset_t objects in userland, when accessing kernland members. - KTR_CPUMASK is changed and now is represented through a string, to be set as the example reported in NOTES.
Please additively note that no MAXCPU is bumped in this patch, but private testing has been done until to MAXCPU=128 on a real 8x8x2(htt) machine (amd64).
Please note that the FreeBSD version is not yet bumped because of the upcoming pcpu changes. However, note that this patch is not targeted for MFC.
People to thank for the time spent on this patch: - sbruno, pluknet and Nicholas Esborn (nick AT desert DOT net) tested several revision of the patches and really helped in improving stability of this work. - marius fixed several bugs in the sparc64 implementation and reviewed patches related to ktr. - jeff and jhb discussed the basic approach followed. - kib and marcel made targeted review on some specific part of the patch. - marius, art, nwhitehorn and andreast reviewed MD specific part of the patch. - marius, andreast, gonzo, nwhitehorn and jceel tested MD specific implementations of the patch. - Other people have made contributions on other patches that have been already committed and have been listed separately.
Companies that should be mentioned for having participated at several degrees: - Yahoo! for having offered the machines used for testing on big count of CPUs. - The FreeBSD Foundation for having sponsored my devsummit attendance, which has been instrumental. - Sandvine for having offered offices and infrastructure during development.
(I really hope I didn't forget anyone, if it happened I apologize in advance).

MFaltix: Add support for Pre-Boot Virtual Memory (PBVM) to the loader.
PBVM allows us to link the kernel at a fixed virtual address without having to make any assumptions about the physical memory layout. On the SGI Altix 350 for example, there's no usuable physical memory below 192GB. Also, the PBVM allows us to control better where we're going to physically load the kernel and its modules so that we can make sure we load the kernel in memory that's close to the BSP.
The PBVM is managed by a simple page table. The minimum size of the page table is 4KB (EFI page size) and the maximum is currently set to 1MB. A page in the PBVM is 64KB, as that's the maximum alignment one can specify in a linker script. The bottom line is that PBVM is between 64KB and 8GB in size.
The loader maps the PBVM page table at a fixed virtual address and using a single translations. The PBVM itself is also mapped using a single translation for a maximum of 32MB.
While here, increase the heap in the EFI loader from 512KB to 2MB and set the stage for supporting relocatable modules.

Merge binutils 2.17.50 to head. This brings a number of improvements to x86 CPU support, better support for powerpc64, some new directives, and many other things. Bump __FreeBSD_version, and add a note to UPDATING.
Thanks to the many people that have helped to test this.
Obtained from: projects/binutils-2.17

Modify our boot block to pick an output device, without which boot1 will fail on G4 machines. On the assumption that most people using FreeBSD on Apple hardware are not using serial consoles, set boot1's output to screen. This should be revisited. While here, reduce verbosity of boot1.
